The IL1470 Germicidal Radiometer is designed for testing the intensity of germicidal and bacterial UV lamps to make sure they are performing within specifications. The instrument features pushbutton operation and gives direct readouts in effective germicidal radiation, the manufacturer states. This radiometer is available with several detector/filter combinations for measuring low- and medium-pressure lamps. This handheld instrument allows in-situ measurements and is NIST traceable, says the manufacturer. According to the company, it is spectrally weighted to match the IES Luckiesh and DIN standard germicidal effective irradiance curves from 250 to 310 nm.
